Abstract

"ARQUITETURA DE SISTEMA HIDRáULICO DE COMANDO DE ORIENTAçãO". A invenção se refere a uma arquitetura de sistema hidráulico de comando de orientação compreendendo pelo menos um acionador (1) de comando de orientação que comporta câmaras, o sistema hidráulico comportando um distribuidor (6) ligado a um dispositivo de geração de pressão (50) e a uma reserva principal (51) associada, o sistema hidráulico comportando ainda uma unidade de bomba eletricamente acionada bidirecional (12) com duas portas, e o sistema hidráulico sendo equipado de um seletor geral (5) disposto para, em um modo normal de funcionamento, colocar em comunicação as câmaras do acionador (1) com o distribuidor (6) e em um modo alternativo de funcionamento, colocar em comunicação as câmaras do acionador (1) com as portas da unidade de bomba eletricamente acionada (12). Um dispositivo de compensação (9, 15, 19, 20) permite, no modo alternativo, compensar um fluxo diferencial entre o fluxo aspirado pela unidade de bomba eletricamente acionada (12) de uma das câmaras do acionador (1) e o fluxo recalcado pela unidade de bomba eletricamente acionada (12) na outra câmara do acionador (1).
